Gyms in Kunming -
Powerhouse (宝力豪)
Just awful. Way way overpriced, I think this year it's 3500 for a year! The trainers are no good, sometimes it's really busy, nothing really special about the equipment, and since it's on the 7th floor, the air is AWFUL in the summer. (they have AC units but when I was there there was only 3 for the whole place and one was broken.)
Surmount (超越)
Better than Powerhouse by far. More equipment, better air, and usually don't have a problem fighting over equipment. Only one squat rack - yea, for some reason they love smith machines over here. Surmount is around 300 a month, but if you go there near Spring Festival time I got a deal for the whole year for 1400, which was nice.
Right now, I'm actually using Yunnan University Gym (云南大学健身室). The equipment very very old, but the price is amazing. You can go for 13 times for 50 kuai! You can squat, deadlift, they have dumbbells etc (everything I need at least). One of the guys that runs the place is an ex-pro martial artist/weightlifter and he's been pretty much giving me free lessons ever since I've been going there...definitely worth it for me! My advice overall though is just stay away from Powerhouse and you'll probably be best suited for a mid-range gym like Surmount or HaoHeng, but if you have any questions feel free to PM me!
